This doesn't mean Facebook should get a free pass. If anything it should get less of a pass because governments love to use the hands of corporations to do what they do (e.g. Hollywood blacklists of communists back in the day, dipping into Facebook's or Google's data stash with a warrant, etc.).
At this point private corporations 'helping' the government is exactly the worrying part because the government at least has some decorum and is keeping up some pretenses and you have to really be in the wrong place, at the wrong time and have an ethnicity that somewhat matches the supposed crime.
Meanwhile with corporations it's starting to look like a free for all between machine learning, big data, hidden internal Terms of Service kangaroo courts and so on. You can get blacklisted, flagged, (shadow)banned and not even know it. And then government or other corporation buys that Big Data DB and real fun starts.
If the government actually wants to capitalize on the data it has there is a lot of instant red tape applied. You can't just get arrested, told you're a terrorist and put in jail for 10 years with 0 process, 0 appeal and 0 documents (well, except with Gitmo but it's a special case).
Meanwhile the corporations can turn you into a functional half-leper in the modern increasingly online society and deny you business arbitrarily (or even secretly) as hell because their deep learning said so (and what they feed in there, what comes out, who made it and how - you don't get to know that), they don't care enough to admit a mistake and the most appeal opportunity you get is customer support ran by lobotomy patients. There's 0 recourse to being shadowbanned, hellbanned, blacklisted, whatever, sometimes even 0 contact option other than making a new account (which breaks their ToS in itself) and unlike the government that has watchful eyes on it from all sides for abuses you'll be told it's "a private business so they can do anything" or that you deserved it because it's a Cool and Good Company.
There was a story that some Palestinian guy got arrested because Facebook translated his "good morning" in some Arabic dialect into "attack them"[0]. If it wasn't the Israeli police arresting him but instead Facebook doing some deep mind big data crap and covertly flagging him as a potential terrorist then he might have found out 5 or 10 years from now that he can't get a plane ticket because some airline or other secretly sourced Facebook's DB and he has no way to even find out where that flagging came from because corporations are free to be secretive in their decision making.
Government also follows some logic (simplistic, biased, populist, racist or reductionist - sure, but still), while corporations can just spit out a verdict with 0 explanations with a link to 20 page ToS written in pseudo-lawyer pseudo-English and say that a video making fun of a mass shooter is suitable for advertisers and one of eating a carrot in a silly hat or swinging a banana around (it's not an euphemism, I mean an actual banana) is not[1].
